{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This interactive visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node labeled by country name. The layout uses a horizontally-oriented tree structure where nodes are positioned based on depth and rendered as text elements with varying font sizes. Built with D3 v5, the visualization employs `d3.tree()` for layout computation, `d3.hierarchy()` for data structuring, and `d3.linkHorizontal()` for generating curved link paths between nodes. The SVG rendering includes zoom functionality via `d3.zoom()`, with data loaded from a JSON file containing the hierarchical country classification.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/632e1cc62bc448178cb589757cebe1ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
